I have a Meade - #65RS manual declination control for Starfinder or DS-16 equatorial scope. This one is optimised for a JMI Electric Declination Motor control. It has a Meade #38 Electric Declination motor with it that I will throw in if you want. The nylon wheel has a one spot that is more worn than the rest, but it is very funtional. The only difference between the JMI and the Meade is the wheel attached to the adjusting rod. You get both. The Meade is free, the JMI wheel is ready for their motor. Asking $110. I pay S&H. Prefer PayPal.
